| abstract |
The invention relates to compounds of the formula wherein AAN is a bivalent radical consisting of one to five bivalent α-amino acid residues, which is N-terminally connected to the radical R 2 and C-terminally to the NH- group, AAC is a bivalent radical consisting of one or two bivalent a-amino acid residues means which N-terminal is connected to the group -C = 0 and C-terminal to the radical R I , R 1 is hydroxyl, etherified hydroxy, amino or substituted amino with the exception of an amino radical derived from an a-amino acid, and R 2 is hydrogen or an acyl radical with the exception of an optionally N-substituted acyl radical of a natural amino acid, furthermore salts of such compounds with salt-forming groups. The compounds are suitable as gag protease inhibitors. |
